Attaching an external mouse, keypad or keyboard
The TrackPoint is disabled automatically.
Attention: If you want to use a serial or USB mouse, you need to
connect the mouse, and disable the TrackPoint (see “Disabling the
TrackPoint” on page 56, then restart the computer).
If you want to use both the external numeric keypad and mouse at
the same time, first connect the keypad cable to the computer; then
connect the mouse cable to the connector at the rear of the keypad .
